It is when we apply session info to the image window we unmaximize, so
don't apply session info to the image window when all we do is
switching tabs in single-window mode.
Implement GtkWidget::focus() and override GtkContainer's focus()
implementation which would always give focus to the canvas because it
is focussable. Instead, try navigating in the focussed overlay child
first, and use GtkContainer's default implementation only if that
fails (which happens when focus navigation leaves the overlay child).
- app/widgets/gimptextstyleeditor.c: don't block all key events so
they can reach the canvas.
- app/display/gimpdisplayshell-callbacks.c: instead, ignore canvas key
events when the canvas has no focus.
This fixes navigating out of the text style editor with TAB, moving
focus to the canvas. I have no clue why navigating *between* the
widgets in the style editor doesn't work.
because it's sealed and deprecated. I don't remember why this code was
there at all (it should never be needed), so I added warnings that go
off if the widget's focus state doesn't match the received event.
and as a "side effect", speed up rendering the image significantly:
- disable double buffering on the canvas widget.
- implement background clearing ourselves (needed after turning off
double buffering).
- remove any fiddling with clipping regions on the tool drawing GCs
and pull the pause/resume code out of the actual image expose
function.
- if there are overlay widgets on the canvas, implement double
buffering manually to aviod flicker, but do it in a way that keeps
pausing/resuming the active tool *outside* the double buffered
drawing.
Session manage empty- and single-image window separately. So when
starting up, the default 2.6 UI is the same. But when enabling
single-window mode, the image window will become much larger then the
empty-image window. These conceptually different windows will then
from that point be session managed separately: switching mode switches
size of the image window.
Refactor session management with the "gimp-empty-image-window" in
GimpImageWindow. In particular, only have one entry point to
gimp_dialog_factory_add_foreign() and remove the is_empty instance
struct member.
Update Windows->Toolbox menu entry depending on if toolbox exists. If
an existing toolbox will be raised, set "Toolbox". If it will create a
new toolbox, set "New Toolbox". We need this special treatment since
there can be only one toolbox, so "New Toolbox" will remove any
toolbox docks from Recently Closed Docks. If we would just have
"Toolbox" it could be misinterpreted as "get me the toolbox I just
closed".
Instead of including dialogs/dialogs.h everywhere, introduce
gimp_dialog_factory_get_singleton(). The dialog factory singleton is
still initialized by dialogs.c though.
Right now the assumption is that we never will have another dialog
factory instance around. There were so many problems before when we
had four of them, so let's just keep one of them around.
We only have one dialog factory now, and
gimp_dialog_factory_from_name() doesn't provide compile-time type
safety, so use global_dialog_factory directly instead.
